She was built to disappear, and that may be the most important thing about her.

In the long shadow of the Cold War, USS Benjamin Franklin did not chase enemies or make headlines. She waited. Silent, hidden, and relentlessly prepared, she carried a responsibility that most Americans never saw and rarely thought about. As one of the last of the “41 for Freedom,” she formed the quiet backbone of a strategy that bet the nation’s survival on submarines no one could find and crews no one would ever know.

Named for Benjamin Franklin, born January 17, 1706, a man who understood that real power works best when it does not announce itself, this submarine embodied the same philosophy beneath the sea. For nearly three decades, she stood watch through Polaris, Poseidon, and Trident, evolving with the times while never changing her purpose.

This is the story of a warship whose greatest victories were the wars that never came.
